=========================================================

之前运行eclipse执行android应用都没问题，今天突然出问题了，控制台报错：

The connection to adb is down, and a severe error has occured.

You must restart adb and Eclipse.

Please ensure that adb is correctly located at 'E:/setups/android/android-2.1_r01-windows/tools/adb.exe' and can be executed.

在命令行下运行 adb start-server

errors:

* daemon not running. starting it now *

ADB server didn't ACK

* failed to start daemon *

已经确认adb.exe的路径没有问题，重启了两次模拟器和eclipse还是不行，上网查了下资料~

解决办法：

（1）查看任务管理器，关闭所有adb.exe

（2）重启eclipse即可
